Weblogic8.1 and Axis 1.2 (Final) :: NullPointerException

Mon, 30 May 2005 17:12:54 -0700

Hello, I wanted to use document style webservices so I moved to Axis 1.2 (Final). I built a simple webservice (RPC style) to see how Axis 1.2 works.. It did go well with Tomcat 4.1. I deployed the same war file in weblogic8.1 SP4. It was deployed successfully but when I try to call from the client it was giving the following error.
 
org.apache.axis.utils.XMLUtils - Failed to set EntityResolver to null on DocumentBuilder
java.lang.NullPointerException
 at weblogic.xml.jaxp.ChainingEntityResolver.popEntityResolver(ChainingEntityResolver.java:61)
 at weblogic.xml.jaxp.RegistryDocumentBuilder.setEntityResolver(RegistryDocumentBuilder.java:168)
 
 
I attached the detailed stack trace in the attached txt file. I did following thing to resolve this but could not get through this..
 
1. I kept the jar files saaj.jar, xercesImpl.jar, xml-apis.jar, jax-rpc.jar in the weblogic classpath before webservices.jar
 
Based on stack trace, apache.utils.XMLUtils is probably sending some XML which is not being able to get through the weblogic document builder.
 
If you guys have any idea please throw some light on this..
 
Thanks for your time
Kiran
